The objective of this article is to enable a more secure remote access method, SSH, while disabling an insecure method of remote connection, Telnet, on Force10 S-Series Switches
To enable SSH, disabled by default, and to disable Telnet, enabled by default, complete the following:
1. Enable SSH via the CLI using a console or Telnet connection saving the configuration.
Dell> Dell>en Dell# Dell#configure Dell(conf)#ip ssh server enable Dell(conf)#crypto key generate Dell(conf)#exit Dell#show ip ssh
SSH server : enabled. SSH server version : v1 and v2. Password Authentication : enabled. Hostbased Authentication : disabled. RSA Authentication : disabled. Vty Encryption Remote IP

2. Test remote access via SSH.
A. Open a terminal emulator program such as Putty B. Enter the ip address of the switch in the corresponding box C. Set the Connection type to SSH D. Click on Open E. Login to the switch via the CLI
Failure to test a successful login via SSH prior to disabling Telnet could result in the loss of remote access to the switch.
3. Disable Telnet and save configuration from a Putty session via SSH using the CLI.
